MATERIAL-HANDLmG MACHINE.

Application led 'May 29,

T o all whom t may concern.'

Be it known that I, Anonrni W. BYBncx, a subject of the King of Sweden, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Material-Handling Machines, of which the 'following is a description, referencebeing had to the accompanying drawing, which is a part of this specification.

This invention relates to certain new and useful improvements in material handling machines and refers more particularly to a cement mixing machine having a distributing boom along which travels a distributing hopper, the boom being mounted for lateral or swinging movement to permit discharge of the distributing hopper at any desired point.

The present manner of swinging the dis- 'tributing boom is by a hand wheel located adjacent the operators platform, the hand wheel working a worm whichr is in ymeshk with a worm wheel made fast to the boom. This construction serves to swing the boom, but is objectionable as oftentimes the operator is occupied with some of his many other duties and, as a result, the men working with the material are delayed.

Therefore, it is one ofthe objects of this invention to provide a distributing boom capable of being swung to anyy desired position independently of the operator controlled means for swinging the boom.

Another object of kthis invention resides in the provision of a distributing boom having a pivot which is journaled in the machine frame structure and'carries a locking member normally urged to engagement with another member mounted yabout the boom pivot whereby the boom maybe readily swung to any desired position and then locked in such position. J

- This invention has for a further object to provide a distributing boom 4mounting whereby the boom may be readily swung to any position Vby means operated from lthe operators platform of the machine orby meansindependent of the first `mentioned means and capable of operationy from any point along the boom.

A seu further Object of this invention `resides in the provision of anjimproved distributing boomvmounting of the,r class described which may be readily applied to l shown. f ff 1922. Serial No. 564,488.

machines without materially increasing the cost of manufacture thereof and which may be applied to machines either at the time of theirmanufacture or to machines now in use.

With the above and other objects in view which will appear as the description proceeds, Vmy invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter' described and more particularly defined by the appended claims, itbeing understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the'fscope of they claims.

In the accompanying drawings, I have illustrated one ycomplete example of the physical embodiment of my invention yconstructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Referringnow more particularly to the accompanying drawing, in which like numerals designate like parts throughout the several views, the numeral 5 designates two upwardly and inwardly inclined side brace beams, but one being illustrated in the drawing, positioned .oneat each side of the discharge''cpening of a mixing drum, not

Locking member 17 is longitudinally s lidably mount- 'ed within a guideway 18 formed in'a'pollar or yoke member 19V fixed to kpivot 7 and carries a shank or'gnide stem' 2O o n'itsin'iier end Wl'iichpa'sses through 'an opening 21 ina web 22 closing the inner 'end o'f the'gnidewa 1. f
